The periodic table is probably the most iconic image in science. Join me to hear the story about its origins, from ancient philosophers speculating about the nature of matter to the earliest chemists who tried to find the mysterious connection between the elements. Learn about Döbereiner's chemical traids, De Chancourtois' 'Telluric screw', Mendeleev's amazing predictions, and much more!
